I read on comp.sys.cbm archives that this power supply used a rectifier to cut the 9V down to 5V, and eventually due to heat/age, the regulator would short and you would end up with 9V on the 5V output, which isn't too nice to the C64 logic... > And, do you have pictures of this PSU, so I can be sure which exactly you mean? Yeah, see here: http://home.icequake.net/~nemesis/misc/c64-psu1.jpg http://home.icequake.net/~nemesis/misc/c64-psu2.jpg This is after cracking the shell off and trying to chip some of the epoxy off -- you can see a heat/ground plate exposed on the right side of the picture. > I think it's simple to reverse engineer the PSU. I would think so too, if I had a way of getting rid of this brick of epoxy without destroying the circuit.... -- Ryan Underwood, <email@example.com> Message was sent through the cbm-hackers mailing list
